arm_hwcap is a global variable, and we should avoid using it as much
as we can. Instead of checking arm_hwcap, we can check whether
regcache->tdesc is a certain kind of target description. This is
what this patch does.

* linux-arm-low.c (arm_fill_wmmxregset): Don't use arm_hwcap.
Use regcache->tdesc instead.
(arm_store_wmmxregset): Likewise.
(arm_fill_vfpregset): Likewise.
(arm_store_vfpregset): Likewise.
